Bob:
No Comments on what you said about misuse of chemicals. Where I did my
work, The beekeeper was open and honest with me. We tried to get to the
bottom of this queen failure. Our thoughts were going on the direction of
queen quality causing the problem, but research proved that we were wrong.



I don't know what generic strips you are talking about. please explain?

Answer: It is a nice way to put the stuff that you mentioned in the top
part of your e-mail.

Bob:
After four years of using coumaphos in the Midwest by most beekeepers we
have yet to see resistance and checked ALL hives in many yards.

Answer: As you are aware that Coumaphos resistance was reported in three
states Maine, Florida and New Jersey. If beekeepers are able to continue
using effectively Coumaphos it should be good news to everyone.

Bob,

U.S. bee inspectors tried Apistan on coumaphos resistant mites in Florida
and did not get any control at all.

Answer: where we did the test, I applied the strips for three weeks and we
got good results. Remember, the USA is a big country, we can't make
general statement that apply to everybody.


Bob: your statement"to solve the problem, replace combs in the brood
chamber" is true. This beekeeper used to replace combs in brood chamber,
but he got tired of keep replacing queens in hives that suffer from queen
failure. It becomes expensive.

Thanks again to Medhat for his post. I get many direct emails from high
profile USDA people which all read BEE-L but do not post . Many pass on
information to me because they know I will not tell the source of the
information received.

Medhat: Some of us are lucky and connected, eh!
